To allwhom it may concern:

Be it known that I, ALBERT H. C. BnA'r'rr, a citizen of the United States, residing at Independence, in the county of Jackson and State of Missouri, have invented a new and useful Smoke-Consumer, of which the following is a specification.

This invention relates to smoke consuming attachments for stoves, house furnaces, upright boilers and the like, one of the objects of the invention being to provide means whereby the smoke given oif during the combustion of fuel within the stove will be mixed in predetermined proportions with fresh air admitted to a supplemental combustion chamber whereby practically complete combustion is effected.

A further object is to provide a controlling valve or damper operable from a point outside of the stove or furnace for varying the proportions of air and combustion products.

A further object is to provide a structure of this character which is simple, durable and eflicient and which can be applied -to stoves, house furnaces and upright boilers of the general type herein disclosed.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention. In the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure 1 is a front perspective view of a stove having the present improvements. Fig. 2 is a central vertical section therethrough parts being removed. Fig. 3 is a perspective view of the supplemental partition and damper used in connection with the stove and forming the principal part of the present invention.

Referring'to the figures by characters of reference 1 designates the casing of a stove and within which is arranged an ash pit 2, and a fire pot 3. A smoke outlet 4 is located adjacent the top of the casing.

In order to effect practically complete combustion of the fuel, air inlet ports 5 are formed within the casing near the top thereof and a suitable damper 6 is provided for regulating the admission of air through the lnlets.

Erected within the casing 1 and below the airinlets 5 is a partition 7 having a conical top portion while its peripheral portion constitutes-a dome-like deflector having a series of depending lugs 8 adapted to be secured in any suitable manner to the casing 1, said partition fitting snugly within the casing. The upper or conical end of'the dome is formed with a plurality of segmental openings 9 arranged about a pivot stud 10, these openings being spaced apart 'at regular intervals. The dome-like or deflecting portion of the partition is designed to direct products of combustion toward said openings. A rotary damper made up of segmental wings 11 is mounted on the stud 10 and is supported by the top of the partition 7. These wings'are slightly shorter than the segmental openings 9 but their width is such that, when. the damper is moved to closing position, the said Wings will extend throughout the width of the openings, thus completely closing said openings except at their outerends where arcuate. slots will be left, as will be apparent by referring to Fig. 2.

One of the wings 11 has an ear 12 fgrmed with an opening 13 designed to receive the downturned inner end 14 of an actuating rod 15. This rod is slidably mounted within an opening 16 in the casing 1 and has a handle 17 whereby it can be conveniently grasped and actuated. An L-shaped bracket.

18 is mounted within the casing 1 and serves to limit the upward movement of the rod 15. A recess 19 is formed in one wall of one of the openings 9 and is designed to receive the depending end 14: when the damper is turned to closed position.

It will be understood that during the combustion of fuel, the gaseous products will pass upwardly through the slots provided at the ends of the dampersegments 11 provided said damper is in closed position. The combustion products will become mixed within the upper or supplemental combustion chamber 20, with fresh air admitted through the inlets 5. Thus a practically complete combustion of the gaseous prod ucts passing into the chamber 20 will be effected before the escape thereof into the outlet 4 and, consequently, there will be practically: no smoke issuing from the outlet. Bymanipulating the damper 11 by means of rod 15 and by manipulating the damper 6, the proportions of air and gaseous products of combustion can be regulated to secure the most desirable results.

It will be obvious that a structure such as herein described can be applied readily to" house furnaces, upright boilers and the like,

the operation in each instance being .the same as that herein described.

Vhat is claimed is I The combination With a stove having a smoke outlet adjacent the top of the casing thereof, of an attachment including a partition insertible into and fitting snugly Within the casing, means for securing said partition in the casing, the said partition dividing the interior of the easing into a lower or combustion chamber and an upper supplemental chamber, said. partition having a conical top portion formed With segmental openings radiating from a common center, a pivot element upstanding from and fixed to said center, that portion of the partition between the conical top portion and the periphery constituting a dome-like deflector for directing products of combustion toward the segmental openings, a damper mounted for rotation on 52nd element and comprising a plurality of segmental Wings, each Wlng being shorter than the segmental openings, an actuating rod slidable in the casing of the stove and having a depending terminal engaging one of the Wings, said terminal being adapted to ork Within one of the segmental openings and to be limited in its movementby the Walls of the opening whereby thedamper Will be held in position either over or removed from the openings, there being a slot in the Wall of one of the openings for the reception of said depending portion of the rod When the damper is in closed position.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of two Witnesses.
